 - `yarn install --no-lockfile` and select the latest package version for the `@mdn/browser-compat-data` package
 - `yarn update`

+This should save the `css-properties.json` JSON file directly in `devtools/shared/compatibility/dataset/`.
+
+For the browsers data, we need to update the RemoteSettings collection.
+While connected to the Mozilla Corporate VPN (See https://mana.mozilla.org/wiki/display/SD/VPN), log into https://settings-writer.stage.mozaws.net/v1/admin/#/buckets/main/collections/devtools-compatibility-browsers/records (Using `OpenID Connect (LDAP)`). Then copy the authentication header using the icon in the top toolbar.
+You can then run `SERVER=stage AUTH='XXX' yarn update-rs-records`, replacing `XXX` with the value of the authentication header.
+
+The logs should indicate if the collection was updated, and if so, provide a short summary of the modifications.
+If the collection was updated, then run Firefox, and use the [RemoteSettings DevTools WebExtension](https://github.com/mozilla-extensions/remote-settings-devtools) to use the `Stage (preview)` environment.
+Then open the compatibility panel and make sure that the updated browsers do appear in the `Settings` panel.
+
+If everything looks right, you can run the same command, on the prod server this time: `SERVER=prod AUTH='XXX' yarn update-rs-records`
 
 Check that all tests still pass. It is possible that changes in the structure or contents of the latest dataset will cause tests to fail. If that is the case, fix the tests. **Do not manually change the contents or structure of the local dataset** because any changes will be overwritten by the next update from the official dataset.
